WILLIAM LEVI CANNIFF, OF JANESVILLE, WISCONSIN, ASSIGNOR-TO THE PARKERPEN COMPANY, OF JANESVILLE, WISCQNSIN, A CORPORATION OF WISCONSIN.

PEN-GRIPPING DEVICE.

My invention relates to receiving and holding devices for pens, pencilsand the like, and particularly to devices that have recently becomeknown as desk sets, in

6 which apen receiving receptacle is secured to a base, which isselectably positioned on a desk.

The object of my invention is to prov de for such a pen receiving andholdlng means, a gripping device which will be positively and immovablysecured in the penreceiving receptacle and which will y1eld 1ngl y holdthe pen in position. This invention is an improvement of the deviceshown and described in the joint application of Horace 'L. Blackman andOscar B. Hjorth, Ser. No.

138,841, filed Oct. 1, 1926. In the Blackman-Hjorthapplication, theydepend upon bosses on the gripping device, entermg into recesses in thepen receptacle, to hold the gripper in proper position. My object is toprovide an anchoring and securing means for this gripping device whichWlll positively keep it permanently positioned, so that it cannot bedisplaced by the pressure of the pen when it is inserted thereln.

My invention consists of certain details of construction, hereinafterset forth, pointed out in my claims, and illustrated in the accompanyingdrawings in which- Fig. 1 shows a side elevation View of a desk set witha pen inserted therein, a portion of same being in section;

Fig. 2 shows a sectional view of the pen receiving receptacle and itsmeans of mounting in the base, the gripper device being shown in fulllines properly mounted therein; and

Fig. 3 shows a detail view'of the gripplng device.

Referring to the accompanying drawings, the reference numeral 10 is usedto indicate the base of 'the desk set; 11, the socket in which ismounted a ball 12 secured on the lower end of a pen receiving receptacle13. The ball 12 has a stem 14 extending up wardly therefrom, which isscrew-threaded to receive and mesh with the screw threads on the base ofthe pen receiving receptacle 13. The stem 14 is provided with a centralopening 15 into which the pen 16 projects when it is inserted and seatedin the receptacle.

The pen receiving receptacle 13 has a shoulder 17 formed on the internalwall thereof and designed for purposes herein- I a smooth surface to thepen point section of the pen, to avoid scratching the pen when it isinserted in the gripper. Also depending from the annular portion 18, Ihave provided a plurality of legs 22 which, by construction, are -of theproper length, that when the gripper is inserted in the recep tacle,(the'upper edge of the annular portion 18 engaging the shoulder 17 andthe receiving receptacle 13" screwed down to its seating against theball 12, the lower ends of the'legs 22 will abut the upper edge of thestem 14. This provides for firmly and securely wedging the gripper meansinto the receptacle. The mounting of the pen gripper and its positioningwith relation to the pen receiving receptacle 13 and the stem 14 on theball 12, and the function of the fingers 20 of the gripper, do notdiffer from the functions and construction of these parts as set out inthe Blackman-Hjorth application above referred to, and therefore willnot be further described, as both the Blackman-Hjorth application andthis application are owned, by assignment, by The Parker Pen Company, ofJanesville, \Visconsm.

Having thus described my invention, what I regard as new and desire tosecure by Letters Patent of the United States is:

1. The combination with a pen holding receptacle of a pen gripper formedof resilient material and designed. to be inserted in the pen holdingreceptacle, said gripper comprising an annular member, a plurality offingers which extend from one side thereof, said fingers being bentslightly inwardly,

.and a plurality of legs depending from the extend from one sidethereof. said fingers being bent slightly inwardly, and a plurality oflegs depending from the annular member.

3. The combination with a pen holding receptacle having an internalshoulder adjacent one end of a pen gripper mounted in said receptacleand abutting said shoulder, the said pen gripper comprising a slottedannular portion, a plurality of. fingers which extend from one sidethereof, said fingers being bent slightly inwardly, a portion of theedges of said fingers being turned back, and a plurality of legsdepending from the annular member.

4. The combination with a pen holding receptacle of a pen grippermounted therein, having downwardly and inwardly extending resilientmembers for gripping the pen point section, and a positioning bardepending from the body of the gripper.

5. The combination with a pen holding receptacle having a ball on oneend, there being a neck or stem on said ball, threads cut thereon whichare fitted to threads cut on the internal wall of the pen holdingreceptacle, there being a central opening in said stem into which thepen point may enter of a pen gripper formed of resilient materialmounted in said receptacle, a positioning bar depending from the body ofthe gripper, its end abutting the upper end of the neck, or stem, on theball when the parts are in operative position. 1

6. A pen gripper formed of resilient material comprising a slottedannular portion, a plurality of fingers which extend from one sidethereof, said fingers being bent inwardly, and a plurality of legsdepending from the annular member.

7. A pen gripper formed of resilient material comprising a slottedannular portion, a plurality of fingers which extend from one sidethereof, said fingers being bent inwardly, a portion of the edges ofsaid fingers being turned back, and a positioning bar depending from theannular member.

8. The combination with a pen holding receptacle of a pen grippermounted therein, having downwardly and inwardly extending resilientmembers for gripping the pen point section, and a positioning bardepending from the body of the gripper.
